Mixing

- Stir constantly using electric mixer or hand for around 10-15 minutes. Mix in a thorough fashion to get a paste like, creamy consistency.
- Prevent formation of lumps during mixing.
Application
- Apply a single coat of primer before applying putty and dry it overnight. This is recommended by some manufacturers while some do not.
- The first coat must be applied in a vertical fashion of bottom to top by making use of trowel/ spatula/ putty blade etc.
- Allow first coat of putty to dry for 6 to 8 hour

- Following the first coat, begin application of second coat of putty.

- Drying time may differ as per thickness, humidity, and temperature.
These are all same aspects about using wall putty for finishing walls.
